The main idea of the plot is to show the ordinary work of an SBU officer who, by force of circumstances, finds himself in the zone to carry out a task. The essence of fashion is ordinary and simple. Stalking in its purest form. Artifacts, anomalies, mutants and mysteries that the main character needs to solve. New story branches have been added to the game, almost all locations have been redone. A lot of new content has been implemented, additional story branches that do not intersect with the main plot, but at the same time significantly help in research and search. The passage still remained non-linear. The order of taking and completing story and quest branches is not tied to each other.
